Biology

  1. hi everyone,

    i am doing my upgrading before i apply for nursing and i am doing my biology homework and i am stuck on a problem. is there anyone that can help me. the question is.....

    how many nucleotide base pairs are found in a segment of dna (gene) that codes for an enzyme protein with 132 amino acids?

    any help would be great.

    thanks j

    do you remember the term "codon?"

    codon= triplet of adjacent nucleotides in the messenger rna chain that codes for a specific amino acid in the synthesis of a protein molecule.

    so if you have 132 amino acids and it takes 3 nucleotide base pairs to code for 1 amino acid, then 132x3= 396
